What three properties do optical telescopes have aid astronomers?
1) light-gethering power, 2) resolving power, and 3) magnifying power
What can astronomers learn by studying star properties?
Very nice one...... 1. The astronomers predict the distance between us and star. 2. The astronomers predict the age of star. 3. By noticing the intencity of light they predict the star is going away or coming near.

Why is the concept of an astronomer continuously peering through a telescope not valid today?
There are a number of reasons why the cartoon image of the astronomer peering through his telescope eyepiece is outdated. 1. The advent of film and then digital imaging has made it possible to do long exposures to see things that are invisibly faint to the eye. 2. The astronomer looking through the telescope has no way to accurately record what he sees. 3. Telescope platforms are in the cold, thin air at the tops of mountains. If the air in the observatory was heated, the heat shimmers would degrade the images. 4. Astronomers are people, too; they don't want to spend all of their nights freezing on mountaintops when they can be at home with their families. 5. With computer-controlled telescopes, digital imaging and the Internet, the astronomers can be at home at their universities in the valley and enjoy the social life, and still present last-night's observations on the big screens in their classrooms each afternoon.
What are 3 types of energy collected by telescopes?
Visible light: Telescopes collect photons in the visible light spectrum to observe celestial objects. Infrared radiation: Telescopes sensitive to infrared radiation detect heat emitted by objects in space that are not visible in the visible light spectrum. Radio waves: Radio telescopes capture radio waves emitted by astronomical sources, providing valuable information about the universe.
What are 3 basic categories of astronomical observation?
The three basic categories of astronomical observation are optical, radio, and space-based. Optical observations involve using telescopes to detect visible light; radio observations involve detecting radio waves from celestial objects; space-based observations are done using telescopes and satellites positioned outside Earth's atmosphere to observe different wavelengths of light.
Why are astronomers finding planets with half the mass of Jupiter?
There are three main reasons for this phenomenon: 1). Those objects exist. 2). Technology has advanced to the level capable of identifying them. 3). Astronomers are looking for them.
What is the instruments for studying the stars?
Star temperatures are determined through various calculations regarding its relative size, distance, and color. the principle of dopler effect is use full to measure the temperature of stars..
